Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a cell measurement configuration method and apparatus.
Background
A dual connection technology is introduced into Long Term Evolution (LTE) Release 12, so that a User Equipment (UE) can simultaneously utilize resources of two LTE base stations to perform data transmission, which not only can improve data throughput rate, but also can improve mobility.
For a UE configured with dual connectivity, a Master base station (Master eNB, MN) connected to the UE is responsible for transmission of Radio Resource Control (RRC) signaling, and a Secondary base station (Secondary eNB, SN) is responsible for configuration and management of a Secondary serving Cell (SCell). The SN only transmits data, and the SN configured auxiliary serving cell group needs to be sent to the UE through the MN through RRC signaling. Both the MN and the SN may configure multiple serving cells to the UE.
With the continuous development of wireless technology, the third generation partnership project (3)rdGeneration Partnership Project, 3GPP) will introduce a fifth Generation mobile communication Technology, 5G, in which a New Radio Access Technology (NR) is adopted to cope with the demand of larger data volume and smaller transmission delay. Operators have widely deployed LTE networks, so in order to fully utilize the existing LTE networks, in the early stage of NR network deployment, the NR network may not be deployed independently and may cooperate closely with the LTE network (light Interworking), and an LTE-NR dual connectivity technique may be used so that UEs and UEs may cooperate with the LTE networkThe data transmission is performed using the LTE network and the NR network.
Before establishing the LTE-NR dual connectivity for the UE, the UE accesses the whole network through an LTE base station. The LTE base station is used as a main base station of the UE and configures measurable adjacent cell information for the UE, so that the LTE base station can select an optimal cell for the UE as a serving cell of the double-connection auxiliary base station according to a measurement result reported by the UE. The LTE master base station needs to configure appropriate NR system frequency point measurement information for the UE. And when the LTE main base station selects the optimal NR cell for the UE, sending a message to the UE to trigger the UE to establish double connection. After the LTE-NR dual connection is established, the selected NR Cell becomes the Primary and Secondary serving Cell (PSCell) of the UE. Through the discussion and decision of the 3GPP conference, the secondary base station can independently control the management of the secondary serving cell in the LTE-NR dual connectivity. The secondary base station may send the configuration information directly to the UE. After the LTE-NR dual connectivity is established, both the LTE primary base station and the NR secondary base station may configure the frequency point measurement of the other side for the UE for the purpose of performing handover or load balancing between the base stations.
Because LTE and NR belong to different systems, an LTE main base station configures NR service frequency point measurement configuration for UE, and an NR auxiliary base station selects a measurement event between different systems (inter-RAT) when configuring the LTE service frequency point measurement configuration for the UE. Inter-system measurement events defined in LTE are class B events, including B1 events and B2 events. The B1 event is described as follows: the measurement result of the adjacent cell of the different system is higher than a threshold; the B2 event is described as follows: the measurement result of the main service cell is lower than the threshold 1 and the measurement result of the adjacent cell of the different system is higher than the threshold 2.
If LTE system measurement events are used for carrying out LTE-NR dual-connection measurement configuration on UE, namely the LTE main base station configures NR service frequency point measurement for the UE, or the NR auxiliary base station configures the LTE service frequency point measurement for the UE, the selection of events B1 and B2 can cause unnecessary measurement and measurement report, the power consumption of the UE is increased, and precious wireless signaling resources are wasted.

Detailed Description
In 5G, it is assumed that a plurality of NR base stations are deployed in a coverage area of a cell under the jurisdiction of an LTE base station, and if a UE first accesses an LTE network, in order to subsequently configure dual connectivity of LTE and NR, that is, configure an NR base station as an SN, an LTE master base station needs to configure the UE to measure a frequency point of an NR system, so that the UE measures a cell of the NR frequency point, and searches for an optimal NR cell for the UE.
Referring to fig. 1, a schematic diagram of a dual connection in an embodiment of the present invention is shown. In the specific process of configuring the dual connectivity, an LTE main base station (MN) can send a dual connectivity configuration request to an NR auxiliary base Station (SN), the NR base station configures wireless parameters for UE and then returns a dual connectivity configuration response message to the LTE base station, the LTE base station sends the wireless parameters configured at an NR side to the UE, and the UE accesses an optimal NR cell according to the wireless parameters configured at the NR side, successfully establishes the dual connectivity and provides communication service for the UE. This optimal NR Cell is the serving Cell of the UE, and may be referred to as a Primary Secondary Cell (PSCell) 12. The primary serving cell 11 of the LTE primary base station may be regarded as a neighbor cell of the NR cell, and accordingly, the PSCell 12 of the NR secondary base station may be regarded as a neighbor cell of the LTE cell.
Because LTE and NR are different systems, when the LTE primary base station configures NR service frequency point measurement configuration for the UE, or when the NR secondary base station configures LTE service frequency point measurement configuration for the UE, an inter-RAT event should be selected, that is, the LTE primary base station or the NR secondary base station performs measurement configuration using a class B event.
And if LTE-NR dual-connection measurement configuration is carried out for the UE by using the LTE system measurement event, namely the LTE main base station configures an NR service frequency point for the UE, or the NR auxiliary base station configures an LTE service frequency point for the UE, and events B1 and B2 are selected. Since the UE is after LTE-NR dual link establishment, the LTE master base station has selected a best NR cell for the UE. After the dual connectivity is established, the LTE master base station may configure the UE to perform measurement of the NR service frequency point, and the UE may measure all cells of the indicated NR service frequency point according to measurement configuration information sent by the LTE master base station. The PScell may always satisfy the B1 event configured by the LTE master base station, and thus, the UE is triggered to report the measurement report of the PScell to the LTE master base station, and the LTE master base station does not need the measurement result of the PScell at this time, which causes unnecessary measurement and measurement report.
Correspondingly, the NR secondary base station may configure the UE to perform measurement of the LTE service frequency point, and the UE may measure all cells of the indicated LTE service frequency point according to measurement configuration information sent by the NR secondary base station. The PCell of the LTE main base station can also be regarded as a neighbor cell of a different system of the NR cell, and the signal quality may be good because the PCell under the LTE service frequency point is used as the main service cell of the LTE main base station. If the NR configures a B1 event, it may happen that the PCell cell of the LTE primary base station always satisfies the B1 event, thereby triggering the UE to report the PCell cell measurement report to the NR base station, and at this time, the NR secondary base station does not need the measurement result of the PCell, resulting in unnecessary measurement and measurement reporting.
In summary, in any of the above cases, unnecessary measurement and measurement reporting may be caused, power consumption of the UE is increased, and precious radio signaling resources are wasted.
In order to solve the above problem, in the embodiment of the present invention, after the inter-system multi-connection is established in the user terminal, in the process that the first base station configures the measurement service frequency point of the radio access network corresponding to the second base station for the user terminal, the measurement configuration information may indicate that the measurement and measurement report of the user terminal on the serving cell under the inter-system service frequency point are limited, so that unnecessary measurement and measurement report may be avoided, power consumption of the user terminal may be reduced, and radio signaling resources may be saved.
In order to make the aforementioned objects, features and advantages of the embodiments of the present invention more comprehensible, specific embodiments accompanied with figures are described in detail below.
Referring to fig. 2, a flowchart of a cell measurement configuration method according to an embodiment of the present invention is shown. The details are described below with reference to specific steps.
When the judgment result is yes, step 22 is executed. And when the judgment result is negative, ending the flow.
In a specific implementation, the inter-system multi-connection may include an inter-system dual-connection. The first base station and the second base station in the inter-system multi-connection can be in a main-auxiliary relationship, and the first base station and the second base station respectively correspond to different wireless access networks. For example, the first base station is a primary base station and the second base station is a secondary base station. For another example, the first base station is a secondary base station, and the second base station is a primary base station.
In an embodiment of the present invention, when the first base station is a master base station and the second base station is a slave base station, the first base station is an LTE base station, and the second base station is an NR base station. Or, the first base station is an NR base station, and the second base station is an LTE base station.
In another embodiment of the present invention, when the first base station is a secondary base station and the second base station is a primary base station, the first base station is an NR base station, and the second base station is an LTE base station. Or, the first base station is an LTE base station, and the second base station is an NR base station.
It can be understood that, in practical applications, the first base station and the second base station may also be other types of base stations, which are not described herein.
In a specific implementation, after the UE establishes the inter-system multi-connection, sometimes to achieve the purpose of load balancing, the first base station may need to configure a measurement service frequency point of the radio access network corresponding to the second base station for the UE.
For example, in an LTE-NR dual-connectivity system, an LTE master base station configures an NR cell measurement service frequency point for a UE, so as to switch the LTE system to an NR system, and convert the LTE system into the NR-NR system to achieve the purpose of load balancing. For another example, in an LTE-NR dual-connection system, an LTE service frequency point is configured in an NR cell, and an NR secondary base station configures service frequency point measurement of the LTE cell for a UE, so as to convert the NR system into an LTE system and into LTE-LTE dual-connection, thereby achieving a purpose of load balancing.
In specific implementation, when a first base station needs to configure a measurement service frequency point of a radio access network corresponding to a second base station for a UE, measurement configuration information is set for the UE. And the measurement configuration information indicates that the UE limits measurement and measurement reporting of the serving cell under the service frequency point of the different system.
For example, the inter-system multi-connection is an LTE-NR dual-connection, the first base station is an LTE master base station, and the second base station is an NR secondary base station. When the LTE master base station needs to configure an NR service frequency point for the UE, the UE may be instructed in the measurement configuration information sent to the UE to limit measurement and measurement reporting of a serving cell at the NR service frequency point.
For another example, when the NR secondary base station needs to configure an LTE service frequency point for the UE, the NR secondary base station may instruct the UE to limit measurement and measurement reporting of a serving cell under the LTE service frequency point in measurement configuration information sent to the UE.
According to the scheme, after the user terminal establishes the inter-system multi-connection, in the process that the first base station configures the measurement service frequency point of the wireless access network corresponding to the second base station for the user terminal, the measurement configuration information can indicate that the user terminal is limited to measure and report the service cell under the inter-system service frequency point, so that unnecessary measurement and measurement report can be avoided, the power consumption of the user terminal is reduced, and wireless signaling resources are saved.
In a specific implementation, the measurement configuration information may include: a measurement object list, a measurement identifier list and a reporting configuration list. And one measuring object in the measuring object list corresponds to one frequency point and is used for indicating the UE to measure on the frequency point. The UE can obtain information of each neighboring cell on the frequency point, and perform measurement on the neighboring cells. Each reporting configuration in the reporting configuration list may include a reporting trigger event, where the reporting trigger event is used to instruct the UE to determine whether to perform measurement reporting according to measurement results of the serving cell and the neighboring cell. Each measurement identifier in the measurement identifier list may associate the measurement object with the reporting configuration. The UE may measure each measurement identifier, that is, measure a neighboring cell on a frequency point indicated by a measurement object associated with the measurement identifier, and determine whether a reporting trigger event in a reporting configuration associated with the measurement identifier is satisfied according to an obtained measurement result.
In specific implementation, the UE may be indicated in the measurement configuration information in various ways to limit measurement and measurement reporting of the serving cell under the different system service frequency point.
In an embodiment of the present invention, a measurement object blacklist may be set in the measurement configuration information, and is used to indicate a serving cell under a different system service frequency point where the user terminal prohibits measurement and reporting, where the measurement object blacklist includes: and identification information of the serving cell under the inter-system serving frequency point.
For example, in LTE-NR dual connectivity, when the LTE master base station needs To configure NR serving frequency points for the UE, the measurement object may be selected as NR in a measurement object cell in the measurement configuration information, that is, the measObjectNR is selected, and a measurement object Black list (Black Cells To Add ModList) is configured in the measurement object cell. And the blacklist of the measurement object comprises the identification information of the service cell under the NR service frequency point. The identification information of the serving Cell under the NR serving frequency point may be indicated by a Cell Index (Cell Index) or a physical Cell identification range (physcelllidrange).
For another example, in LTE-NR dual connectivity, when the NR secondary base station configures an LTE service frequency point for the UE for load balancing and other requirements, in a measurement object cell in the measurement configuration information, a measurement object may be selected as EUTRA, that is, a measObjectEUTRA is selected, and a measurement object blacklist (Black Cells To Add ModList) is configured, where the measurement object blacklist includes identification information of a service cell under the LTE service frequency point. The identification information of the serving Cell under the LTE serving frequency point may be indicated by a Cell Index (Cell Index) or a physical Cell identification range (physcelllidrange). When the UE performs cell measurement according to the measurement service frequency point indicated in the measurement configuration information, the UE does not perform any measurement and measurement reporting operations on the cell indicated in the measurement object blacklist.
By the scheme, the measurement object blacklist is set in the measurement configuration information, and the user terminal can be instructed to prohibit measurement and measurement report of the service cell under the different system service frequency point in the measurement object blacklist, so that unnecessary measurement and measurement report can be avoided, and the power consumption of the UE and the wireless signaling resource are saved.
In another embodiment of the present invention, a reporting trigger event may be set in the measurement configuration information, where the reporting trigger event includes any one of: the measurement result of the neighbor cell of the non-service cell of the different system is higher than a preset first threshold value; and the measurement result of the main service cell/the main and auxiliary service cells is lower than a preset second threshold value, and the measurement result of the neighbor cell of the different system non-service cell is higher than a preset third threshold value.
In particular implementations, the measurement results may include at least one of: reference Signal Receiving Power (RSRP) and Reference Signal Receiving Quality (RSRQ). It is understood that, in practical applications, other factors capable of characterizing the quality of the cell service signal may also be selected, and are not described herein.
In a specific implementation, the neighbor cell of the inter-system non-serving cell may be other neighbor cells except for the serving cell under the inter-system serving frequency point, or may be a neighbor cell under the inter-system non-serving frequency point.
In a specific implementation, for convenience of description, the reporting trigger event may be: the measurement result of the neighbor cell of the non-serving cell of the inter-system is higher than a preset first threshold, which is called a B3 event. Reporting a trigger event: the measurement result of the primary serving cell/the primary and secondary serving cells is lower than a preset second threshold, and the measurement result of the neighbor cell of the non-serving cell of the inter-system is higher than a preset third threshold, which is called a B4 event.
For example, in LTE-NR dual connectivity, a B3 event in the reporting trigger event corresponding to the LTE master base station may be: the measurement result of the non-service cell of the NR system is higher than a preset first threshold value; the B4 event may be that the primary serving cell measurement result is lower than a preset second threshold and the NR system non-serving cell neighbor measurement result is higher than a preset third threshold. The preset first threshold, the second threshold and the third threshold may be set by the LTE master base station according to an actual application scenario.
For another example, in LTE-NR dual connectivity, a B3 event in the reporting trigger event corresponding to the NR secondary base station may be: the measurement result of the non-service cell neighbor cell of the LTE system is higher than a preset first threshold value; the B4 event may be: and the measurement result of the main and auxiliary serving cells is lower than a preset second threshold value, and the measurement result of the adjacent cell of the non-serving cell of the LTE system is higher than a preset third threshold value. The first threshold, the second threshold, and the third threshold may be set by the NR secondary base station according to an actual application scenario.
By adopting the scheme, the B1 and B2 events in the existing B-type events of the LTE system are enhanced to obtain enhanced reporting trigger events, namely the B3 and B4 events, and if the measurement objects related to the reporting trigger events are different system service frequency points, the B3 and B4 events are adopted, so that the measurement report of the user terminal on the service cells under the different system service frequency points can be forbidden, unnecessary measurement reports are prevented from being sent to corresponding base stations, and the energy consumption and wireless signaling resources of the UE are saved.
In specific implementation, a mode of setting a measurement object blacklist in the measurement configuration information can be independently adopted, so that measurement and measurement report of a user terminal on a service cell under a different system service frequency point are limited. Or, the reporting trigger event can be set in the measurement configuration information separately, so as to limit the measurement and measurement reporting of the service cell under the different system service frequency point by the user terminal. The measurement and report of the service cells under different system service frequency points by the user terminal can be limited by adopting a mode of combining setting a measurement object blacklist in the measurement configuration information and setting a report trigger event in the measurement configuration information.

As can be seen from the above, after the inter-system multi-connection is established at the user terminal, in the process that the first base station configures the measurement service frequency point of the radio access network corresponding to the second base station for the user terminal, the measurement configuration information can indicate that the user terminal is limited to measure and report the serving cell under the inter-system service frequency point, so that unnecessary measurement and measurement reporting can be avoided, the power consumption of the user terminal is reduced, and the wireless signaling resources are saved.
